A system for detecting vibrations from a surface is provided. The system includes a coherent light source for projecting a multi-beam pattern onto the surface and an imaging device for mapping a speckle field generated by each spot formed on the surface by the multi-beam pattern to a unique region of an imaging sensor. The system further includes a processor for processing speckle field information received by the imaging sensor and deriving surface vibration information.

Arrangement for controlling a component having multiple states includes a device that generates a signal at a frequency that enables it to be conducted through a human body, and a conductive surface coupled to the device, situated in a position accessible by a part of the human, and which enables proximity or contact of the part of the human to the conductive surface to develop a reactive coupling between the human and the conductive surface. The component has multiple, different states and is controlled by the human to change from a first state to a second state upon completion of an electrical circuit including the component, the conductive surface and the device upon developing reactive coupling between the human and the conductive surface when the device is generating the signal conducted through the human. The component may be a vehicular component such as a door or window.

A radar sensor system and method for ascertaining whether an unattended child is present within an automotive vehicle. The radar sensor system carries out the method and includes a transmitter, at least one sensor, and processing circuitry. The method includes the steps of: illuminating at least one occupiable position within the vehicle with radiation of multiple frequencies; generating radar sensor signals from reflections of the transmitted radiation, a plurality of the radar sensor signals corresponding to different frequencies; and operating the processing circuitry for generating and determining if a first indicator value indicative of motion in the occupiable position satisfies a first predetermined criteria and, if so, generating and determining a second indicator value indicating a degree of repetitive pattern within the radar sensor signals, and determining presence of an unattended child in the vehicle if the second indicator value satisfies a second predetermined criteria.

A vehicle safety system and method is provided for preventing heat related injuries in hot cars. The system includes a sensor, to sensing the presence of a child or animal in a stationary vehicle; and a controller, configured to issue an alert in response to the detection of the presence of the child or animal in the vehicle. The controller may also be for controlling a change in temperature in the vehicle in response to detection of the presence of the child or animal in the vehicle.

A system for detecting hot car seat situations, manually cooling the child in those situations, and facilitating one or more alert notifications is disclosed. An apparatus receives sensor data that it uses to detect the presence of a child in a car seat in a vehicle. Multiple sensors provide added security against false positives. When a child is detected, the apparatus activates a cooling flow of air towards the child if the temperature rises above a threshold. The apparatus waits until the vehicle is not moving and off before initiating notifications to one or more subscribing devices. Once off, and once the temperature of the child further rises or has the air flow on for a period of time, the apparatus sends a notification to the subscribing devices. If the child is not removed within a set period of time, then emergency responders are notified.

An occupant detection system and method may include a user interface and at least one sensor to determine if there is an occupant in the vehicle. In one embodiment, the system and method use capacitive sensing sensors embedded into a cushion and/or back of seats in a vehicle. The capacitive sensor sends a sense signal to a controller and the controller would recognize various conditions such as an empty seat or a seat occupied by a person or animal. It could also determine if there was a child seat in a position on a vehicle seat and if there is a child in the child seat.

A car seat pressure sensor device with wireless communication includes a wireless transmitter and a pressure sensor assembly. The wireless transmitter is configured for wirelessly communicating with a portable electronic device via a wireless signal. The pressure sensor assembly includes at least one pressure sensor and is interconnected with the wireless transmitter. The pressure sensor assembly is operable to turn on or off the wireless signal from the wireless transmitter. The pressure sensor device is configured to turn on the wireless signal from the wireless transmitter for communication with the portable electronic device when the pressure sensor assembly senses a certain weight, and turn off the wireless signal from the wireless transmitter for communication with the portable electronic device when the pressure sensor assembly does not sense the certain weight.

The present disclosure provides a vehicle occupant detection and alert system including an onboard apparatus including a controller operably connected to an occupancy sensor, an environment sensor and a transceiver. The controller generates a signal indicating that an occupant is present. A mobile communication device is operably connected to the transceiver. The mobile communication device includes a processor which upon execution of instructions performs the steps including:

receiving a signal from the controller indicating that an occupant is in the vehicle, responsive to an alert condition, initiating a first alert mode, wherein a first notification is generated and the functionality of the mobile device is restricted; and

generating a prompt to enter a code to acknowledge the first notification, wherein the functionality restriction is removed in response to entry of the code.

According to a child safety seat with the rotating mechanism provided by the present invention, the seat body is driven to rotate 360 degrees through the toothed ring and the screw rod. The screw rod is more labor-saving and has a simpler structure. The turntable is fixed relative to the seat body. The locking member is arranged at a bottom of the seat body, and the positioning slot is arranged on the toothed ring, to fix the turntable and the toothed ring. By the arrangement of the plurality of positioning slots on the toothed ring and the arrangement of an unlocking switch configured to unlock the locking member and the positioning slots, the seat body can be manually rotated through the turntable, which is faster. By the arrangement of the sensor to sense whether the seat body is locked, the safety of use is improved.
